Maryland Route 310 (MD 310) is a state highway in the U.S. state of Maryland. Known as Cayots Corner Road, the highway runs 3.96 miles (6.37 km) from MD 213 at Cayots east to the Delaware state line east of St. Augustine in southern Cecil County. MD 310 was built east of St. Augustine by 1921 and west to what was then U.S. Route 213 (US 213) in the early 1940s. MD 310 was extended west when US 213 was relocated at Cayots in the early 1950s.
